IMPROVEMENT IN HUB-ATTACHING DEVICES.

Specification forming part of Letters Patent No. 2 11,990, dated February 4, 1879 application filed November 19, 1878.

i a longitudinal section of my improved hub connected to the axle. Fig. 2 is an elevation of the axle separately. Fig. 3 is a cross-section on line 00 .r of Fig. 1.

Similar letters of reference indicate corresponding parts.

The hub A is to be of any desired charac ter and adapted to receive the spokes of the wheel. a, is the metal box of the hub, retained in place by anut, b, at the outer end. 0 is the point-cap of the hub. At the inner end the box (0 extends beyond the hub, forming a prolongation of the hub and a dust-cap, (7., e is an annular groove or recess formed at the inner side of box a.

The axle or spindle B is of usual construction, except that its journal '5 has no thread at the outer end. 0 is the spring-hook, which I prefer to make as a flat spring-tongue, f, connected rigidly to the axle, and with its free end provided with a hook, g, and with lugs or forks h h, that pass at each side of the axle and retain the spring in position laterally. This construction also increases the bearingsurface of the hook.

When the hub is upon the axle the hook g is within the groove 6, the tongue f retaining it in place, so that the wheel and axle are retained together by the shoulder of the recess 0.

I prefer to attach the hook c at the under side of axle B, so that when a jack is placed 111] der the axle to raise the wheel it will press up ton guef, and the wheel can then be drawn oif the hook end g, passing freely through dustcap (I.

The recess 6 also constitutes a chamber that retains any grease that escapes from the journal, and prevents it from getting upon the outside of the hub.

The connection of the hub to the axle by the described arrangement is firm and reliable, as well as simple, and there are no parts to be detached in taking off the wheel.

If desired, a movable stop may be placed upon the axle, to prevent any inward movement of the hook when in place; but with a strong spring such a device would not be required. V

I am aware that it is not new to hold the hub of a wheel to its axle by means of a spring catch or a pivoted hook-lever, either of said devices being secured to the axle; but

What I claim as new and of my invention 1s- The flat spring f, arranged on the bottom of the axle between the prongs of a bifurcated head, 1 h, the part g serving as a hook or catch to work in a groove, 0, of journal-box, and the arms h h embracing the angular portion of axle, as shown and described.
